● Purpose

The KCB series stainless steel gear oil pump is suitable for conveying lubricating oil or other liquids with properties similar to lubricating oil, which does not contain solid particles and fibers, is non corrosive, has a temperature not exceeding 80 ℃, and a viscosity of 5 × 10-6~1.5 × 10-3m2/s (5-1500cSt).

● Application scope

Can be used as a transmission and booster pump in oil transportation systems;

Can be used as a fuel pump for delivery, pressurization, and injection in the fuel system;

A hydraulic pump that can be used to provide hydraulic power in hydraulic transmission systems;

In industry, it can be used as a lubricating oil pump;

● Structural characteristics

The KCB series stainless steel gear oil pump mainly consists of gears, shafts, pump bodies, protective valves, and shaft end seals. The gears have high hardness and strength after heat treatment, and are installed together with the shaft in a replaceable shaft sleeve for operation. The lubrication of all parts inside the pump is automatically achieved using the output medium during pump operation.

There are oil discharge and return grooves inside the pump, which cause the gear to bear less torque force during operation, resulting in less bearing load and less wear on the pump.

The pump is equipped with a protection valve as overload protection. The total reflux pressure of the protection valve is 1.5 times the rated discharge pressure of the pump, and it can also be adjusted according to actual needs within the allowable discharge pressure range. However, please note that this protective valve cannot be used as a pressure reducing valve for long-term operation. If necessary, it can be installed separately on the pipeline.

From the extended end of the spindle towards the pump, it rotates clockwise.

The reasons for the vibration of KCB series stainless steel gear oil pumps are diverse, and users may encounter such titles during stable use. Users should follow the standard operation in order to find the cause of vibration of stainless steel gear oil pumps from the source, which can effectively avoid the probability of vibration during use. Another simple and easily overlooked reason for the vibration of stainless steel gear oil pumps is that they are equipped with mismatched motors. In this case, it is also possible to cause vibration of the stainless steel pump. If the equipment is not fair, it is easy for both the pump and motor to be easily damaged. The longer it is used, the greater the degree of pump wear. Exceeding the load pressure of the stainless steel gear oil pump itself will correspondingly cause severe vibration of the stainless steel gear oil pump.

Some users may experience vibration during the use of stainless steel gear oil pumps. What is the reason for this situation? The appearance of vibration in the stainless steel gear oil pump is corresponding to the defect of internal protrusion in the stainless steel gear oil pump. To avoid such a situation, what are the principles to follow? From a device perspective, it is important not to violate regulations by carefully reading product manuals during use and equipping motors during use to reduce human induced vibrations to a relatively low level.

During the operation of the stainless steel gear oil pump, due to the continuous operation of the transmission shaft, it is easy to cause the transmission shaft to rotate. In the future, the stainless steel gear oil pump will continuously roll, which will affect the operation of the oil pump. If this situation is assumed to occur, there will be many sequelae, such as damage to other components of the bearing. Regarding the abnormality and vibration of the stainless steel gear oil pump control valve, we will now conduct a simple analysis for you:

After the installation of the stainless steel gear oil pump stabilizer valve, improper use often causes many malfunctions. If these faults are not eliminated in a timely manner, they will affect the function and service life of the control valve. Common faults mainly include:

1、 The pressure continues to rise after the exhaust of the stainless steel gear oil pump

This is mainly because the selected stabilizing valve has a stable discharge capacity of small flat equipment, and a suitable control valve should be selected again; If the centerline of the valve stem is not aligned or the spring rusts, causing the valve disc to not open to the desired height, the valve stem should be reassembled or the spring replaced; If the exhaust pipe section is insufficient, exhaust pipes that meet the stable emission area should be used.

2、 Valve disc frequency jump or vibration

Mainly due to the high spring stiffness. Springs with appropriate stiffness should be used instead; Improper adjustment of the adjustment ring resulted in excessive reseating pressure. The position of the adjustment ring should be readjusted; The discharge pipeline has excessive resistance, resulting in excessive discharge back pressure. The resistance of the discharge pipeline should be reduced.

3、 The stainless steel gear oil pump does not open at the specified pressure

Mainly caused by inaccurate constant pressure; The spring's elasticity decreases due to aging. Adjust the screw appropriately or replace the spring.

4、 The valve disc of the stainless steel gear oil pump does not reseat after discharge

This is mainly caused by the bent valve stem of the spring, improper installation position of the valve disc, or jamming. Should be reassembled.

5、 Stainless steel gear oil pump leaking

Under normal working pressure of the equipment, there is leakage exceeding the allowable level between the valve disc and valve seat sealing surface of the gear oil pump. The reason is that there is dirt between the sealing surface of the valve disc and valve seat. You can use a lifting wrench to open the valve several times and flush away any dirt; Damaged sealing surface. Repair should be carried out by grinding or grinding after turning according to the degree of damage; The valve stem is bent, tilted, or the lever is misaligned with the fulcrum, causing the valve core and disc to be misaligned. Should be reassembled or replaced; The elasticity of the spring decreases or loses its elasticity. Measures such as replacing the spring and readjusting the opening pressure should be taken.

6、 The control valve of the stainless steel gear oil pump does not open when it reaches the specified pressure

The reason for this situation is inaccurate constant pressure. The compression amount of the spring or the position of the heavy hammer should be readjusted; The valve disc is stuck to the valve seat. Regular manual air release or water discharge tests should be conducted on the control valve; The lever of the lever type stabilizing valve is stuck or the heavy hammer is moved. The position of the heavy hammer should be readjusted and the lever should move freely.
